Pulse oximeters, a type of photoplethysmography (PPG) sensor, are electronic devices that measure a person’s blood-oxygen saturation (SpO 2) and heart-rate (HR) levels. Since their inception in the ...

The use of HPGe detectors is chosen in situations where isotope identification is required due to their excellent resolution. In various circumstances, it is necessary to carry out these gamma-ray ...

Detecting a signal pulse is usually basic electronics, but you start to find more complications when you need to time the signal’s arrival in the picoseconds domain. These include the time-walk effect ...

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2024.240009 , discusses a smart photonic wristband for pulse wave monitoring. Pulse waves are a prominent component of physiological ...

Using a spectrum analyzer for pulsed measurements has always required a careful understanding and knowledge of the parameters of the pulse signal, as well as the subsequent operation of the spectrum ...

The notion of “signal processing” might seem like something impenetrably complex, even to scientists. However, the fact is that most of them have already being doing it for a long time, albeit in an ...

Radar is a remote sensing technique used to detect, locate, and analyze objects by emitting electromagnetic waves, more specifically microwaves, and measuring the time interval between the ...

Digital-to-analog converters (DACs) have been widely used since the 1980s in arbitrary function generators (AFGs) and arbitrary waveform generators (AWGs) to produce signals for verification, ...
